Ch. 421Max Out Proficiency, Grind Until You Become a Mortal Sword Immortal: Part 421
Yun Shu fought the Dragon Bone in the Dragon Pool, gaining the upper hand but failing to damage or control it. After learning that Seventh Realm Mental Energy and a mind-control technique might subdue the bone, he surfaced and began cultivating, leaving the Patriarch doubtful that he could reach that level in time.
- Yun Shu fought the Dragon Bone for half a day, eventually matching its strength and forcing it back without harming it.
- Demons trapped in the Dragon Pool's Illusion Realm waited uneasily as the pool shook and they continued absorbing its power.
- The Dragon Bone attacked Yun Shu with golden source energy, and the Patriarch explained that the energy came from the True Dragon and could strengthen Yun Shu's body.
- Yun Shu asked how to control the Dragon Bone, and the Patriarch said the Illusion Immortal Bead could affect its weak mind but was occupied, while Yun Shu would need Seventh Realm Mental Energy and the Mind Control Secret Technique from One Thought.
- Yun Shu knocked the Dragon Bone back, surfaced, and began cultivating in an attempt to reach the Seventh Realm, while the Patriarch doubted he could do so before the pool closed.
